M.a. Ford 20440620 Solid Carbide Jobber Drill Bit 13/32in

Product Description

The M.A. FORD 20440620 is a solid carbide jobber length drill bit designed for precision drilling in demanding production and maintenance applications. Sized at 13/32 inches (0.4062 inches decimal) in diameter with a 4-1/2 inches overall length, this bit features a 118-degree faceted point angle and a web-thinned, tapered web for reduced thrust and cleaner entry. The bright, uncoated carbide construction provides excellent rigidity and dimensional accuracy, with a diameter tolerance held to -0.0005 to 0.0000 inches. Two spiral flutes with a regular helix and a 5xD flute-to-diameter ratio promote efficient chip evacuation during deep drilling passes. Licensed HVAC techs, machinists, and metalworking professionals rely on this bit for consistent performance in high-volume setups.

The 20440620 is suited for drilling cast iron, non-ferrous metals, stainless steel, and carbon or alloy steel. Its straight-cylindrical shank seats directly in standard drill chucks and collet systems without adapters, making it appropriate for CNC machining centers, drill presses, and hand-held rotary tools used in fabrication shops, mechanical contractors, and industrial maintenance environments. The general-purpose grade and ISO 9001:2015-certified manufacturing make this a reliable choice for shops that need consistent tool performance across mixed-material workloads.

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, and carbon and alloy steel workpieces. Compatible with any drill chuck or collet system accepting a 13/32 inch straight-cylindrical shank. Fits CNC machining centers, drill presses, and rotary drilling equipment configured for jobber length tooling.

Installation Notes

This bit is installed by machinists and metalworking trades using standard drill press or CNC setup procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit. Seat the straight-cylindrical shank fully in the chuck or collet and confirm runout is within acceptable limits before beginning a cut. Coolant-through is not supported on this tool; apply external cutting fluid or mist cooling as required by the workpiece material and cut depth.
